Are you one of those who do not hesitate to push tables and chairs against the die to a maximum of place in the living room, and have the certainty that the session will not be interrupted by a furniture too close? Or are you more of those who do not want to move everything, even if it imposes have to evolve into a smaller area? That's the type of question that interests enormously Valve. The US video game studio has indeed embarked on the development of a virtual reality helmet - on live - which is developed in partnership with Taiwanese manufacturer HTC. But to know which direction to go, he must obtain precise information on how the players will welcome this technology at home.

The arrival of the autopilot in vehicles sold by Tesla Motors is imminent. After a long test phase, the US automaker specializing in electric cars will indeed deploy this week the stable version of its driver assistance (called very simply "Autopilot") via a simple update (7.0) which will be published 15 October. To access the autopilot ", it will be in possession of a recent model of the range S Tesla Motors. Otherwise, the update will still be available to download, but without the possibility to activate the autopilot. This includes "many improvements" and a new interface, according to Elon Musk, although the bulk of the overhaul is planned for a later update (7.1). The operation of this automatic control is based on several factors: there are in particular a camera located at the front, a radar and a ultrasonic sensor which controls the immediate environment around the vehicle, to 360 degrees. Asked about a building mode "Autopilot" Elon Musk confirmed that version 7.0 of the firmware allows the vehicle to park itself in a square in unoccupied parking. It can also keep the car in a queue, including around corners, overtake a vehicle and brake smoothly or strongly depending on what happens on the track. While respecting the rules of the road.

It is 8:30 p.m. when the doors of the Philharmonic 2 close on a public that does not really know what he is about to see. Maelstrom: a contemporary music event which is part of the weekend Turbulence Digital, one of many UFO eclectic program of the Philharmonie. The name of the party was not given the chance. The theme is the whirlwind of notes, ideas, concepts that have the hard task of giving a digital image in current artistic compositions. The visual arts have quickly adopted these new means of expression, with hybrid or fully digital creations and live music made it a part of the show in itself. Giant screens, lighting effects and other holograms rhythm concerts today. Yet the possible field is barely ajar. How to make of digital art that is not a sideline of the work but of a whole? This is the question that the Philharmonic has tried to respond by inviting on stage artists that have made computer-aided visual production new significance to follow with much rigor.

Certainly, for Apple, the Chinese market is not managed like any other. Sometimes he creates good surprises, like when Tim Cook announced that sales of branded products were doing very well despite the Chinese economy crisis of confidence. Other times, it's a problem. As recently as last month, Cupertino discovered that applications created with a botched development environment had forced a passage on its App Store China. Today, the App Store is again pointed SourceDNA by researchers who noticed strange API requests from applications available in China. A third tool to display advertising in applications developed by the company Youmi sending confidential data of users who opened the ads on their devices. 256 applications (one million cumulative downloads) were affected and illegally sent piles of data on private servers advertising.

The 4G / LTE protocol is considered more secure than 3G and a fortiori that the 2G (which was not difficult), but it is not however free from defects that threaten users' privacy. Researchers at the University of Berlin and the University of Helsinki and released this week (.pdf) what they claim to be the first practical attack against publicly disclosed fourth generation networks. Their method reported by The Register is based on a fault of the protocol to reveal the geographic location of an individual in an average area of ​​about 2 square kilometers, also operating applications that can generate notifications at the request of third parties. In this case, they chose to achieve their demonstration attacks via Facebook Messenger and WhatsApp, but the mechanism must be reproducible with Snapchat, Skype, Twitter and many other messaging applications. In practice, GUTI can remain the same for several days. Or, the notification message headers that contain the GUTI are not encrypted. The researchers realized that they learn to know the GUTI a target by collecting the messages transmitted from the base stations 4G / LTE (which requires having all the same an idea of ​​where it is located), and send discreet notifications to victims to follow them to track their movements. The method depends on the applications used by the target. For example if they use Facebook, send a message using a lambda account. It will not trigger notification shown explicitly by the application, but the message will still be sent to the smartphone to land in the tab "Other messages" that nobody ever looks at (or almost).
